Thin coir substrate grow

Hey everyone. So I'm trying a little experiment of my own, I am curious as to whether 1 thick substrate is better than multiple thin substrates as far as end product weight goes. I used 1 brick 650grams of exoterra coir, 2 quarts of vermiculite dash of hydrated lime and handful of gypsum. Used the bucket tek, except I put a turkey bag in the bucket put all ingredients in, pour in 4 quarts boiling water let sit for short time push all air out of bag, use their little ties and put in oven preheated to 200 f. This is not about pasteurization, this is about cooking the coir. Like bod said before mushies seem to like cooked coir.
I'm gonna get flamed for this part but it's what I do.
Cook in oven for a long time, 4 5 6 hours whatever, dont really trip.
Let cool overnight then I tale a quart jar, clean well with alcohol and such, pour 1 packet of fish antibiotics in the jar then fill with distilled water from a fresh jug.
Pour into bag of coir until properly hydrated to field capacity and mix very well. Everyone's gonna have their own thoughts on this but my belief is that as mycelium gets weaker the first thing to attack is going to be bacteria, further weakening it until molds can take hold. Adding the antibiotic gives another line of defense. I seem to get to 6th and 7th flushes with no contains at all. Obviously these are small slow flushes, but they do come.
Anyways, split that amount into 3 66qt tubs and mix with 3 quarts of colonized wbs in each tub then level and I put press n seal over the top of my tubs and tape up all holes. The sub depth is about 1 inch. I don't care if I get small mushies, essentially what I'm trying to do is instead of getting all of my weight and four or five flushes take that same amount littered up thin so essentially giving it a lot of surface area for the same amount of nutrition and water and hopefully get all of the weight in one or two flushes here is some pictures of what they look like right now this is about day 4 since I mixed the grain into the coir. I'll keep it updated until harvest to see what final weights are. I'll have to make a control tub to compare the final weights.

My thoughts on the antibiotics are. Antibiotics can be harsh on fungi but not always. Sometimes even causing morphology difference in yeast for example or lagged performance. Most antibiotics actually come from fungi though.
Bacteria might actually fend off some contaminant molds, maybe not. Which is worse/comes first etc... Just offering this as a counter theory for your investigation. Also are the antibiotics effective against what the problem bacteria species are? If they are does its use open the way for something else to cause just as much issue.
Also you should be using single strain isolates to do comparison tests ideally. Or a huge sample size of variable genetics
